Lili Reinhart Grabs Attention in Stunning Sheer Look for BTS Swim Video
Lili Reinhart has captured the spotlight again, this time in BTS’s new music video for their single SWIM, the lead track from the band’s latest album, ARIRANG. The video premiered on March 20 and quickly went viral, with fans sharing clips and reaction videos across social media.
Many viewers praised the chemistry between Reinhart and the members of the global K-pop group, noting how natural she looked on camera. In the video, Reinhart wears several standout outfits, but one of the most talked-about is a delicate ivory satin gown with sheer lace details on the bodice.
The dress gives a romantic and classic feel that matches the dreamy tone of the song. To add a modern touch, she layers the gown with a long chocolate-brown coat, creating a striking contrast as she moves through the video’s sets. The combination of soft and bold elements made the visuals feel both elegant and cinematic.

Fans online immediately reacted to her appearance, sharing fashion breakdowns and commentary. “She fits perfectly with the vibe of the video,” one fan wrote on Twitter, while another added, “Lili Reinhart is glowing in SWIM, the fashion is everything.”
Within the first day of release, these posts and reaction videos racked up millions of views, showing just how much attention her presence drew. The project also marks a big step for Reinhart as she continues to expand her career beyond television.
After finishing her long-running role on Riverdale, she has been choosing projects carefully and focusing on her production company, Small Victory Productions, which aims to support character-driven stories.
For BTS, the ARIRANG era is their first full group album since completing their military service in 2025. The album mixes traditional Korean instruments with modern synth-pop, and SWIM has already been called one of the most experimental tracks on the release.
The band plans to begin a world tour in April, with stops across North America and Europe. Including a high-profile Western actress like Reinhart shows how BTS continues to bridge cultures and expand its international influence.
The collaboration between Reinhart and BTS has created a moment that blends the worlds of music and film. Fans and critics alike have praised the video not just for the visuals and music, but for the way it brings together global talent.
By stepping into this project, Reinhart has tapped into a massive new audience while BTS continues to redefine what it means to be a global pop culture powerhouse.
